WebTo solve the problem, this paper proposes a model-free stereo calibration method for binocular fisheye camera based on neural-network. The neural-network can implicitly describe the nonlinear mapping relationship between image and spatial coordinates in the scene. We use a feature extraction method based on three-step phase-shift method.

For example, a checkerboard pattern consists of alternating white and black squares of equal size. The corners of the squares that lie inside the pattern are used as the control points. autocad 画像 トレース 自動
